This gives me a diff between these two commits and is very handy. However, since you merged core-8-6-branch in the bugfix branch I ended up in getting huge changes that are unrelated to what you want me to review. What was the reason for merging core-8-6-branch in the bugfix branch? Did core-8-6-branch contain any fix that is useful in our bugfix branch perhaps?

I don't expect this to be controversial at all, it should be very easy and quick tough. I will happily sponsor it, yes. But we definitely should write a small TIPlet. We require others to do it in such cases, we cannot save the effort here I think/
> Normally, such an extension TIP would target trunk only (that is 8.7), because the 8.6 line is not supposed to receive new features, only bugfixes. In this specific case however, for the reasons you stated, I think we can push this into 8.6.x. Again, that explanation needs to go in the TIP.

>> My little project of fixing the test errors in menubutton.test became a much bigger project after I actually looked at how they were working in the demo and found that they were pretty broken on all platforms. I believe that I have now fixed menubuttons on all platforms. (See the ticket 70e531918e .)

You can specify an index, and then the menu will be posted so that the top left corner of that entry is at the point, instead of the top left corner of the whole menu. On the Mac his allows me to use a built in method of NSMenu , which should be much more robust than trying to compute the geometry of Apple's proprietary menu. (I can and do compute the geometry correctly today, but who knows what will happen with the next Apple OS release?)
